ChIP-seq of Atlantic salmon (Salmo salar) gill exposed to varying winter length

Project description:The experiment is designed to assess the impact of winter length on epigenetic status of key genes related to smoltification. Transferring fish from constant light (LL) to short photoperiod (SP) for different durations and then returning to constant light (LL) for 8 weeks to stimulate smoltification. Three histone marks were assessed: H3K4me3, H3K27me3 and H3K27ac.

The farmed Atlantic salmon (Salmo salar) skin-mucus proteome

Project description:Norway is the largest producer and exporter of farmed Atlantic salmon (Salmo salar) worldwide. Skin disorders correlated with bacterial infections represent an important challenge for fish farmers due to the economic losses caused. Little is known about this topic, thus studying the skin-mucus of Salmo salar and its bacterial community depict a step forward in understanding fish welfare in aquaculture. In this study, we used label free quantitative mass spectrometry to investigate the skin-mucus proteins associated with both Atlantic salmon and bacteria. In addition, the microbial temporal proteome dynamics during 9 days of mucus incubation with sterilized seawater was investigated, in order to evaluate their capacity to utilize mucus components for growth in this environment.

Host-pathogen interaction of Atlantic salmon (Salmo salar) and the ectoparasite, Neoparamoeba perurans in amoebic gill disease

Project description:Marine farmed Atlantic salmon (Salmo salar) are repeatedly susceptible to amoebic gill disease (AGD) caused by the ectoparasite Neoparamoeba perurans over their life cycle. The parasite elicits a highly localized response within the gill epithelium mucosa resulting in multifocal mucoid patches at the site of parasite attachment. This host-pathogen response drives a complex immune reaction within the pathology of the disease, which remains poorly understood. A dual RNA-seq approach was employed using Illumina sequencing technology to investigate both the linteraction between the host and the parasite.

Global gene expresssion profiling the gills of amoebic gill disease (AGD) affected Atlantic salmon (Salmo salar)

Project description:Amoebic gill disease (AGD) is an ectoparasitic condition of some farm-reared marine fish and is caused by Neoparamoeba perurans. Tanks housing Atlantic salmon (Salmo salar) were inoculated with Neoparamoeba perurans and fish were sampled at 36 days postinoculation (pi.). AGD-affected gill tissue was dissected from N. perurans infected fish, and a DNA microarray was used to compare global gene expression against tissues from AGD-naive fish. To determine whether the changes in gene expression were restricted to AGD-lesions, lesion tissue from AGD-affected fish was also compared with non-lesion gill tissue dissected from the same gill arch. Samples were assessed using a DNA microarray. Keywords: comparative gene expression, parasite-induced lesion, Neoparamoeba perurans, amoebic gill disease

Transcriptional changes in Atlantic salmon (Salmo salar) after embryonic exposure to road salt (NaCl)

Project description:The present study aimed to identify the persistent molecular changes occurring in Atlantic Salmon salmon (Salmo salar) eggs after 24h exposure to high concentrations (5000 mg/L) of road salt at fertilization. Atlantic Salmon (Salmo salar) eggs after fertilization were exposed to high concentrations (5000 mg/L) of road salt for 24 h and used for gene expression analysis.

Hepatic transcriptomic profiling reveals early toxicological mechanisms of uranium in Atlantic salmon (Salmo salar)

Project description:To study the short term (48 h) hepatic transcriptional changes and identify potential modes of action, Atlantic salmon (Salmo salar) were exposed to 0.25 mg/L, 0.5 mg/L and 1.0 mg/L depleted uranium. A combination of high density (60 k) custom oligonucleotide salmonid miacroarray and quantitative real-time reverse transcription polymerase chain reaction (qPCR) was employed to perform gene expression analyses. Differentially expressed genes (DEGs) were determined using one-way analysis of variance (ANOVA) and Tukey posthoc tests. Functional enrichment analysis based on Gene Ontology (GO) was performed to link DEGs to their biological functions. The Salmo salar DEGs were further mapped to mammlian orthologs. By using ortholog DEGs, gene networks were built based on well-curated mammlian protein-protein interactions and pathways analyses were performed to link DEGs to specific toxicological/biological functions. The results obtained from microarray analysis were further verified using qPCR.
